CARL EKISS, OF BETHANY, ILLINOIS.

SPRIN G-WHEEL.

Application filed October 29, 1913.

Be it known that I, CARL EKISS, a citizen of the United States, residing at Bethany,in the county of Moultrie and State of Illinois, have invented new and useful Improvements in Spring-Wheels, of which the following is a specification.

The invention has relation to vehicle wheels of the type embodying spring spokes the purpose being the provision of a wheel which will absorb shock and vibration and prevent excessive wear upon the vehicle and parts mounted thereon and add materially to the comfort of the passenger.

The invention provides a wheel of novel formation embodying a sectional rim and having such rim sections connected to the hub by means of spring spokes, the rim being channeled and receiving a tire which in the present instance consists of a wire coil which is seated in the channel of the mm.

The invention consistsof the novel fea tures, details of construction and combination of parts, which hereinafter will be more particularly set forth, illustrated in the accompanying drawings, and pointed out in the appended claim.

Referring to the drawings,forming a part of the specification, Figure 1 is a side view of a vehicle wheel embodying the invention. Fig. 2 is a transverse section of the rim portion of the wheel on the line w-m of Fig. 1. Fig. 3 is a detail perspective view of the outer end of one of the spring spokes.

Corresponding and like parts are referred to in the following description, and indicated in all of the views of the drawings, by the same reference characters.

The wheel which is designed chiefly for vehicles comprises a hub 1, spring spokes 2, sectional rim 3 and tire 4:- The hub 1 is formed with a plurality of faces 5 which form seats for the inner ends of the spokes 2, such spokes being secured to the hub by means of fastenings 6 which may consist of screws, bolts or the like. The faces 5 have an approximate tangential arrangement and are provided at their inner ends with shoulders 7 against which the inner ends of the spokes abut. The spokes 2 curve throughout their length and are formed at their outer ends with heads 8 which curve transversely and longitudinally to conform to the inner side of the rim. The heads 8 are Specification of Letters Patent.

formed with the spokes 2 as a part thereof and are secured to the rim sections 3 by rivets 9 or analogous fastenings. Each of the spokes is formed of a flat bar and is curved throughout its length to approximately' a bow. The spokesare arranged to ranged with spaces between continuous ends of adjacent sections thereby making provision for a limited movement of the sections when the wheel is in active service. The rim sections are channeled in their outer sides so as to form a seat in which the tire 4 is fitted. It is to be understood that a wheel 1 embodying the invention may comprise any number of rim sections and that each of such rim sections may be supported by any number of spokes as shown, each rim section is supported by two spokes the latter being attached at their outer ends to the rim section at the extremities thereof.

The tire 4 preferably consists of a wire coil which is fitted in the channelof the rim and retained in place by the contractile action-of the coilor in any suitable way. This form of tire besides being resilient presents a roughened surface thereby preventing skidding and is also puncture proofand capable of resistingwear and may be adjusted to bring new portions in position to receive the wear as it isobvious that the tire may be turned in its seat in the rim;

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustratlve, and

entially, the spokes being connected at one end with the hub While the heads of the spokes are connected with the rim sections at points adjacent the terminals thereof, a tire member holding the separated rim sections in assembled relation, and means for detachably securing the inner portion of the tire member to the rim sections and the integral heads of the spokes.

In testimony whereof I ai'iix my signature in presence of tWo Witnesses.
